Hello All,

I am facing an issue with cyclicAMI boundary condition for non-conformal meshes. I am solving impeller case. Impeller is Hexahedral mesh and volute is tetrahedralmesh. please find the details here:

s1-to-r1-side-2
{
type cyclicAMI;
nFaces 1008;
startFace 425571;
matchTolerance 0.001;
neighbourPatch s1-to-r1-side-1;
transform noOrdering;

}

s1-to-r1-side-1
{
type cyclicAMI;
nFaces 1926;
startFace 443357;
matchTolerance 0.001;
neighbourPatch s1-to-r1-side-2;
transform noOrdering;

}

The issue is, data is not transfering form these two patches. Like mass is not balancing and also giving very strange results. I am facing this issue with OpenFOAM last version. Current version is also having this issue. Its working fine with conformal meshes. But not with non-conformal meshes.

I checked this boundary conditon in OpenFOAM-1.6-Ext version. There approch is "ggi". ggi is working fine. Mass is balancing.

Any body Can suggest whether CyclicAMI with non conformal meshes will work in OpenFOAM or not?

Please reply....
